Research was focused on understanding the degradation kinetics of cold rolling oil used in the rolling mill at Tata Steel. Aged rolling oil leads to various surface defects. Ageing phenomenon is influenced through thermo‐mechanical behaviour, oxidation, hydrolysis and presence of iron fines. Ageing of cold rolling oil in presence of iron fines was systematically performed at various temperature followed...
Nozzle clogging in roll gap lubrication (RGL) is a pain area for hot strip steel rolling. Nozzle clogging severely affects lubrication affecting rolled surface quality causing prominent hot rolling defects like banding and peel‐off phenomenon in work roll. Uneven coefficient of friction leads to variable or poor lubrication, which raises the chances of cobble and tail chewing in coils, lowers roll...
